Software Supersavers appear to be fuelling the downward trend in software prices and at the same proving that cheap does not ways mean nasty.
The plot is far from original: it's a 'shoot 'em down' game of the space invaders type, but in this version, you can also move your laser base up and down the screen, in addition to the usual lateral movement.
The game is a galactic marathon. There are 60 waves of aliens of every description. I was particularly fond of the little springy alien, a sort of Martian version of Zebedee. Full marks go to the programmer for the attack patterns. The aliens come from every angle and shoot at you in all directions. Only the most adept could possibly survive the onslaught which about an hour.
Graphics and sound are used to good effect. The aliens are mostly of the 3D variety and rotate rapidly. There is a demo mode in which you can shoot the aliens, but they cannot destroy you. This is excellent for practising the upper levels.
